A mirror and source of light are situated at the origin O and a point on OX respectively. A ray of light from the source strikes the mirror and is reflected. If the DRs of the normal to the plane of mirror are `1,-1,1,` then DCs for the reflacted ray are :

A

`1/3,2/3,2/3`

B

`-1/3,2/3,2/3`

C

`-1/3,2/3,-2/3`

D

`-1/3,-2/3,2/3`
